Passing parametric input parameter to batch file

Question

This might be a simple question, but I didn't found any thread, may be I am searching wrong.

I am having a simple bat script and passing some arguments. Currently I am getting the argument based on there order. But I want to make simple for the user.

My current command line looks like: testBatch.bat setupip setupuser setuppass My current batch script looks like:

set setupip=%1 set setupuser=%2 set setuppass=%3 echo I am doing some operation after this based on the input I got.

Now I want to modify the command such that the user should not be woried about the order of argument to pass. Basically I want to see my command like this: testBatch.bat --ip setupip --user setupuser --password setuppass

What modification I have to do in my batch script?

try this:

@echo off for %%a in (%*) do ( call set "%%~1=%%~2" shift ) echo :%--user% echo :%--pass%

if the passed it is called like:

namedArgs.bat --user user --pass pass

the output will be like:

:user

:pass

This will handle also quoted parameters with spaces in them.

Thing you are looking for is called 'Named Arguments'. I found link for same question here.

Answer Which I like from that link is as follow:

set c=defaultC set s=defaultS set u=defaultU :initial if "%1"=="" goto done echo %1 set aux=%1 if "%aux:~0,1%"=="-" ( set nome=%aux:~1,250% ) else ( set "%nome%=%1" set nome= ) shift goto initial :done echo %c% echo %s% echo %u%

Run the following command:

arguments.bat -c users -u products

Will generate the following output:

users defaultS products

Added code snippet from link where I do refered the answer. @PetterFriberg

There is a batch command called shift, which can basically do a shift left on your parameter variables.

So as the start of your script, you need a loop

inside that loop you decode %1 for the 'verb' part of your option with a if statement

inside that if block, you call shift. then old %2 becomes the new%1, old %3 becomes the new %2, etc

so inside that if, you can pick up a secondary argument for the verb, if needed. Then call shift again.

loop until your arguments are empty. Tadah!
